Resolve ESLint findings in Comment Notify CI

Problem/Motivation

The ESLint job in the current 8.x-1.x baseline fails as an allowed failure, so the pipeline reports passed with warnings.

Exact CI findings

Pipeline 911674, job 11344552 reports 8 errors in comment_notify.js: Prettier quote/formatting errors at 2:3, 7:15, 8:70, 9:13, and 11:18; unnecessary strict mode at 2:3; non-shorthand method syntax at 5:5; and prohibited jQuery .bind() at 6:7. Seven are auto-fixable; the event binding requires a focused code change.

Proposed resolution

Format the behavior to current Drupal JavaScript standards and replace deprecated jQuery event binding with .on(), without changing behavior.

Testing instructions

1. Run Drupal core ESLint/Prettier rules against comment_notify.js.
2. Exercise the notification checkbox behavior.
3. Run the complete Comment Notify test suite.
4. Confirm the ESLint CI job passes.
